Part of today's SEO practice is adding links to your web site or blog as
it is well known that more quality links that you have on your web
pages, the more likely Google and other powerful search engines are to
rank you highly in their search engine pages.

If your site or blog is going well you may find yourself being
confronted with a number of requests for links. Your challenge then as a
search engine optimist is to find content that relates to your own.
This is very important as Google will boost you even higher if you are
linking to relevant information that integrates nicely with your own
site. Therefore avoid selling hoodia, no matter how attractive the offer
looks, if your blog or website is about selling winter tires.

Another thing you should check out before you agree to a link
exchange request with anyone is how often the site is indexed. To do
this all you need to do is see when the last time the site was cached in
Google. This is also a good way of making sure you are not linking to a
dead site. People who ask for link requests often fiddle with their
link counters to make it look like they have more visitors then they do!

Yet another consideration is to look at the layout of site. Will
your link be placed somewhere on the site where it will be easy for
readers to see or find. If not then doing a link exchange is not worth
it especially if you are giving the exchange better space than he or she
is giving you! This is why it is advisable to state the page or
placement of where you would like your link to go before you agree to
any kind of link exchange for a blog or web page.
